I can't imagine a reality where a finance company hires a full staff, pays them nothing, and risks money on loans for no financial return whatsover. That's what a "true 0%" from a finance company would look like.
Then it's really simple, don't advertise a 0% interest program if it isn't 0%.
How hard is that?
I understand dealers hands are tied when the company dictates it, my argument is in general, if it's the company then it's the company, but I know for a fact that some dealers are taking advantage of the situation to mark things up even more...which only adds further to the skeptical eye that many buyers have.
I agree SOME of it has to do with how a dealer communicates the price. If I ask for the price of the tractor and he tells me "$25,000 cash" then to me, that is the price, period. As soon as I say finance it he now has to back pedal and explain how or why the price is going to be higher. that isn't winning any customers.
What he should do is tell me the price of the tractor as it sits, before any rebates, cash incentives or any other hullabulla names you want to apply to it.
He should then tell me what the interest rates are for financing it over the various range of months (but the price should not go up!)
Then he should tell me, however if you pay cash, the price will be discounted X$$$.
Then, if he tells me there is a 0% interest for 60 months program, the price SHOULD STILL BE THE SAME as it was initially quoted.
I'm betting few people, if any actually pay cash for something like a tractor. To start off quoting the cash price, including all incentives and NOT tell the customer that price includes those incentives is not a good way to gain their confidence, primarily because you are now going to have to explain a higher price when/if they want to talk financing.
And whatever you do, do not tell someone you have 0% interest and then quote them an even higher price if they choose that option...and then expect them to pay that interest up front in cash!
